WVOODENnSTlRR'UP MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,009, dated August 2, 1881. Application led June 15, 1881. (Model.)

To allwhom it may concern Beit known that I, JonN JAMES MUNGEN, of Danville, in the county of Vermillion and State of Illinois, have invented certain new and useful Improvements in Machines for Making Wooden Stirrups; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a top view of my irnproved apparatus; Fig. 2, a longitudinal vertical section thereof; Fig. 3, a longitudinal vertical section on the line :v of Fig. 1, and Fig.'4'a detached view of one of the cutters.

The invention has relation to machines for making wooden stirrups; and it consistsl in the improvements in the construction of the same hereinafter fully described, and particu larly pointed out in the claims.

In the accompanying drawings similar let ters of reference indicate corresponding parts in the several figures.,

A represents the frame of the planer or machine for cutting theA blanks preparatory to sawing the gains therein.

B represents the frame of the sawing-machine. The rotary cutters or knives C and the gang-saws D are arranged upon the same shaft, E, which traverses the two frames A B, as shown, and is provided with a suitable drum to receive the band from the band-wheel of the engine. Y

An auxiliary frame, F, is pivoted at one end between the side rails of the frame A, and is adjusted at the other end by set-screws a., to

regulate the thickness to which the blank is "to be dressed. This auxiliary frame F has slotted boxes G, which encircle the shaft E to permit the adjustment before mentioned. The

auxiliary frame F is provided with ways H, in which a sliding carriage, I, Works to present the blank J to the cutters C. The carriage I vers L, which are operated to hold or release theblank J at will. An arm, M, projects from the front inner side of the sliding carriage l.

An auxiliary shaft, N, traverses the lower v is provided with clamping-dogs K, having le' rails of the two frames A B, beneath the cutters and saws, and is provided beneath the saws with a friction-pulley, O.

The rear end of the saw-frame B has hinged to its lower end rail a friction-pulley, P, which is operated by a forked arm, Q, connected to a lever, R, pivoted to the side of the frame B, as shown, to operate the carriage I, which is accomplished as follows: A strap or cord, S, is connected to the front end of the carriage I and to the auxiliary shaft N beneath the cutters C, and works over a pulley, b, at the front en-d of the machine. A second strap or belt, T,- is attached to the rear end of the carriage I, and is provided with a Weight, U. This strap works over a pulley, c, at the rear end of the frame. When the lever R is pressed toward the rear of the frame, the friction-pulleys engage, the strap S is wound upon the auxiliary shaft N, and the carriage I is drawn forward, causing the blank J to be presented to the knives G as the carriage I passes over them. When the arm M strikes the lever B it removes the pressure upon the lever, disengages the friction-pulleys, and permits the weight U to run the carriage I back to receive another bla-nk and permit the operation to be repeated.

Above the gang-saws is a hinged table, V, provided with a central opening, d, through which the saws protrude, and with ways W, upon which a sliding frame, X, is operated over the saws by hand to cut the cross-gains in the blank J at the points at which said blank is to be bent to form the stirrup.

In Fig. 5 a plan of one of the knives C is shown, it being straight for nearly its entire length upon its cutting-edge, but having inclines c at each end for the purpose of cutting the blank thicker at the ends than in the central portion.

The hinged table over the saws may be turned up at any time to sharpen the saws conveniently.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is

l. The pivoted frame F, having ways H, and

Weighted carriage I, havin g lever-clumps K L, combined with the shaft E, carrying knives C e, as und for the purpose set forth.

2. The combination ofthe shaft E, carrying knives C e, journaled in the frame A,co1nbined with the pivoted frame F H, adjusting-screw a, weight 'l U, cord S, friction-pulleys 0 P, and operating-lever R, as and for the purpose set forth.

3. In :n wooden-stirrup machine, the combination of the shaft E, carrying` knife C e, and gang-saws D, with the frames A V. pivoted frames F W, and sliding carriages I X, as and for the purpose set forth.
